The program determines for a general equation of 2nd order given as A*x^2 + B*x*y + C*y^2 + D*x + E*y + F = 0 the type of curve ( circle, ellipse, parabola, hyperbola ) and displays details like radius, semi-axes, midpoint and/or angle of rotation. V2.0 now includes a graph of the curve and finds both midpoints for an ellipse (rotated ksi,eta- as well as basic x,y-system).
